Description
Technical field
The utility model relates to the ladder technical field, is specifically that a kind of boats and ships log in ladder.
Background technology
Often carry out the exchange of personnel and goods between boats and ships and land or platform, it is exactly the passage that is used for connecting between boats and ships and land or platform that boats and ships log in ladder.Due to swaying of boats and ships, brought trouble to practical action, particularly in some provisional places without terminal facilities, just more increased difficulty, this just makes boats and ships log in ladder its distinctive characteristics.The problem of bringing in order to overcome oscillation of ship, existing ship log in and exist the equipment complexity in terraced product, and be expensive, the shortcomings such as use is carried constant, and applicable situation is limited, and the oscillation of ship situation is complicated, as swaying, surging, yawing, rolling, pitching, hang down and swing, the part situation that just solved that existing product has is not considered all situations.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of simple in structure, and can be to swaying, surging, and yawing, rolling, pitching is hung down and is swung these situations and can realize that all the boats and ships of regulating log in ladder.
the technical solution of the utility model is, the utility model boats and ships log in ladder, it comprise that two structures are identical and be parallel to each other and over against the parallelogram linkage, be provided with the stair treads that several cross-sectional planes are parallelogram between two parallelogram linkages, each stair treads sequentially evenly distribute along the stock of parallelogram linkage, one side of each stair treads is all hinged with two stocks of a parallelogram linkage, the another side of each stair treads is all hinged with two stocks of another parallelogram linkage, and when the quarter butt of parallelogram linkage is level, each stair treads are all parallel with quarter butt, the end that each flexible direction with a hydraulic actuating cylinder of the two ends of the below quarter butt of each parallelogram linkage is the knock-pin of vertical direction up and down is hinged, and the base of each hydraulic actuating cylinder is equipped with cardan wheel, each hydraulic actuating cylinder all is connected with hydraulic control unit, hydraulic control unit with sway sensor and be connected.
After adopting said structure, the utility model compared with prior art has the following advantages:
The utility model is by two parallelogram linkages or be parallel double crank mechanism, and several cross-sectional planes are the parallelogram stair treads, four hydraulic actuating cylinders, and four four main portions of base with cardan wheel form.wherein the cross-sectional plane of stair treads is parallelogram, every stair treads both sides are connected with the smooth hinge form with two stocks of a parallelogram linkage respectively, the two ends of one quarter butt of two parallelogram linkages are connected with the piston rod of the hydraulic actuating cylinder mode with smooth hinge respectively, this quarter butt effect is equivalent to the rocking bar of parallelogram linkage, it shakes extension and contraction control by hydraulic actuating cylinder, and when the quarter butt of parallelogram linkage is level, described quarter butt (being rocking bar) is parallel with every stair treads, four Barrel of Hydraulic Cylinders are separately fixed on base with cardan wheel, the flexible of each hydraulic actuating cylinder can be controlled separately, the cardan wheel base can move to any direction in the plane,
Owing to being the parallelogram linkage, so no matter the utility model becomes any angle with the deck, no matter that is to say how the shape of parallelogram changes, as long as the rocking bar maintenance level of parallelogram linkage just can make all maintenance levels of stair treads, thereby guarantee that no matter ladder and deck are in the walking which kind of angle can suitable people; Become any angle with the deck by regulating the utility model, can make the utility model be adapted to the situation that logs in of differing heights and distance; Sway situation according to the difference of boats and ships, recompense by regulating the flexible of four hydraulic actuating cylinders, can make the utility model not be subjected to the impact of oscillation of ship as far as possible; The movement in the plane of cardan wheel base can be eliminated boats and ships swaying, surging or yawing to impact of the present utility model; The process of swaying that subtracts of the present utility model is to be controlled the flexible realization of corresponding hydraulic actuating cylinder according to the oscillation of ship status information that detects by hydraulic control unit, groundwork is exactly according to the state that sways that sways sensor (gyro sensor) detection boats and ships, control hydraulic actuating cylinder stretch compensate the change in displacement that swaying of boats and ships causes, keep of the present utility model stable;
During use, the regulator solution cylinder pressure makes the rocking bar maintenance level of parallelogram linkage, and at this moment stair treads are also horizontality; When ship rolling, two cylinders controlling the parallelogram linkage of the utility model one side rise simultaneously or descend simultaneously, control simultaneously two cylinders that boats and ships log in the parallelogram linkage of terraced opposite side and rise simultaneously or descend simultaneously, thereby make stair treads keep horizontality; When the boats and ships pitching, two hydraulic actuating cylinders of left end of controlling each parallelogram linkage rocking bar rise simultaneously or descend simultaneously, and another hydraulic actuating cylinder of controlling simultaneously each rocking bar rises simultaneously or descends simultaneously, thereby makes stair treads keep horizontality; When boats and ships hang down when swinging, control that four hydraulic actuating cylinders rise simultaneously or descend simultaneously, thereby making boats and ships log in the impact maintenance transfixion that ladder is not subjected to the boats and ships up-and-down movement; When boats and ships swaying, surging or yawing, can eliminate boats and ships swaying, surging or yawing to impact of the present utility model by the movement above deck of cardan wheel base;
Comprehensively above-mentioned, the utlity model has simple in structure, and can be to swaying, surging, yawing, rolling, pitching is hung down and is swung these situations and all can realize the advantage of regulating.
As improvement, in the same side and pedal when being level, the hinge-point of every pedal and the hinged formation of top stock is all higher than the hinge-point of this pedal and the hinged formation of below stock, like this, mode of operation of the present utility model can have two kinds: a kind of is to log in terraced pattern, is namely ladder relation straggly between stair treads; Another kind of for logging in plate mode, the approaching coincidence of four bars that is the parallelogram linkage is straight line, this moment, stair treads were connected to each other, be in same plane, form a large flat board, namely flexible by the regulator solution cylinder pressure, also can make the utility model log in plate (or making boats and ships log in trestle) by the boats and ships that stair-stepping shape becomes the one flat plate shape, this can facilitate vehicle up and down or the loading and unloading of article; When not using the utility model, also the utility model can be deformed into tabular, being convenient for carrying, conserve space; When needs log in the plate use with the utility model as boats and ships, as Fig. 2, the left end hydraulic actuating cylinder of each parallelogram linkage rocking bar is shunk, the hydraulic actuating cylinder elongation of rocking bar right-hand member, thereby rocking bar is tilted, four bars of parallelogram linkage are a line close to coincidence, and at this moment the stair treads hypotenuse also overlaps mutually and forms a monoblock flat board; Eliminating boats and ships, to log in the principle that principle that plate rocks and above-mentioned elimination the utility model time that is ladder stands to rock identical, be adjusting be to remain unchanged for the angle that makes rocking bar.
As improvement, the right-hand member of the top quarter butt of each parallelogram linkage all is connected with connected unit, like this, makes use of the present utility model more flexible.
